Title: Control of fuel and air supply to burners
Inventor: PAGE HAROLD ARTHUR
IPC: F23N5/18
Filed: 1962-12-06
Abstract: 980,365. Fuel and air supplies to burners. COCHRAN & CO. ANNAN Ltd. Dec. 5, 1963 [Dec. 6, 1962], No. 46102/62. Heading F4T. [Also in Division G1] Apparatus for maintaining constant the relative proportions of air flow and fuel flow to an oil or gas burner comprises an electric bridge circuit A including a resistance 14 which has a high resistance-temperature coefficient and is arranged in the air stream to the burner, and a relay 4 responsive to changes in the balance of the bridge and arranged to control a reversible electric motor 1 actuating a fuel valve 1A. The bridge comprises the resistance 14, another resistance 15 and the two parts 16, 17 of a potentiometer. The resistance 14 is heated by an electric heater 28; if therefore the air flow changes the balance of the bridge is upset and a pair of solenoids 7, 8 in the arms of the bridge cause the relay 4 to move from its neutral position to engage one or other of two fixed contacts 5, 6 to energize the motor 1 in one direction or the other to open or close the fuel valve 1A. The motor also actuates the movable contact 18 of the potentiometer to restore the balance of the bridge. The air flow is controlled manually or by a device 27 responsive to the pressure or temperature of the steam in a boiler heated by the burner. The device 27 moves the movable contact 21 of a potentiometer D to unbalance a second bridge circuit which is associated with solenoids 12, 13 and a relay 9 controlling a second electric motor 2 actuating an air valve 2A. The motor also actuates the movable contact 24 of the second bridge circuit C to restore the balance of the bridge. In a second embodiment, Fig. 2 (not shown), a potentiometer is arranged across the two resistances 14, 15 of the bridge circuit A and the movable contact thereof is mechanically linked to the movable contact 21 of the second bridge circuit C. Two resistances bridge the potentiometer D of the second bridge circuit C and one of these resistances has a high resistance-temperature coefficient and is disposed in the heated air stream to the burner. Any movement of the control device 27 causes simultaneous unbalancing of the two bridge circuits and consequential adjustments to the fuel and air valves. If the temperature of the heated air to the burner changes the bridge circuit C causes adjustment to the air valve to maintain the rate of air flow constant. In another form of the invention a single bridge circuit is provided and includes an unheated resistance which is subjected to changes in temperature of the air flowing to the burner. When a permanently heated resistance is used an unheated resistance may also be used so that the balance of the bridge is not influenced by changes in air temperature.

Filed: 1961-12-23
Abstract: <PICT:0953609/C3/1> <PICT:0953609/C3/2> Skins or hides 11 draped over a horse 10 are transferred one at a time to the feed roller 12a of a "double-acting" (i.e. both sides of skin processed simultaneously) processing machine and thereafter transferred to a horse 13, by a transfer means comprising an arm 14, or intermittently moving conveyer provided with spaced pick-up elements 15, 16 having suction cups 15a, 16a (or clips, hooks, forks &c.), the arm 14 being reciprocated mechanically or electrically between the two positions, Figs. 1 and 3, in timed relationship with the operation of the machine 12, the latter incorporating a sensing device 30 for this purpose. The horse 13 may be substituted by a drying machine having skin supporting poles whose movement is synchronized with the transfer means.  By providing a further pick-up element the transfer means may be used to pass skins through two single-acting machines arranged in series.  In all cases the movement of the skins is effected in line with the longitudinal axis of the feed roller(s) of the processing machine(s).

Filed: 1961-12-29
Abstract: 1,041,565. Cathode-ray tube displays; tran-- sistor pulse circuits. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Dec. 27, 1962 [Dec. 29, 1961], No. 46668/61. Headings H3T and H4T. In an arrangement for tracing alpha-numeric characters, symbols &c. by appropriate deflections of the beam of a cathode-ray tube in two co-ordinate directions, a plurality of pairs of symbol generators is provided for the respective deflection control means each pair being pre-set to produce a sequence of deflection signals appropriate to a different symbol &c. and selectively connectable to the deflection control means in accordance with the symbol &c. required. The symbol generators (Fig. 2, not shown) may comprise circuits having a plurality of inputs energized in turn by a shift register and producing a stepped signal, e.g. of the type designated "Basic X," "Basic Y" in Fig. 1. The signals are then supplied via pairs of gates G (Fig. 2), in accordance with the setting of a symbol selector, to integrating circuits which " smooth " the stepped signal to produce deflection signals as indicated in Fig. 1 by the waveform "Integrated X," " Integrated Y," for application to the X and Y deflection control means. At the end of the sequence required to produce a symbol the gates close automatically (unless the same symbol is to be repeated) and a shift signal, generated by moans similar to the symbol generators but " unsmoothed," applied to the X deflection control means so that the next symbol is displaced from the preceding one. The arrangement may be developed by the provision of " word " generators which, when operated by the shift register, successively actuate the symbol generators to produce the required word, sentences, mathematical formulµ &c. (Fig. 3, not shown). The integrators for "smoothing" the stepped deflection waveform comprise a PNP transistor T 1  (Fig. 4, not shown) to the base of which the stepped waveform is applied and the emitter circuit of which is completed via a constant current device consisting of a PNP transistor T 2  and resistor R 2 . The output from T 1  is fed via a diode D to a capacitor C provided with a constant current charging circuit comprising a NPN transistor T 3  and resistor R 1 . Thus as the input voltage rises (i.e. goes more negative) diode D is cut-off and C changes via T 3  and R 1  until the potential at A reaches that of the emitter of T 1  whereas when the input voltage falls (i.e. goes more positive), T 1  cuts-off and C discharges through D and T 2  and since the latter is a constant current device the amount by which C discharges is equal to the current which previously flowed through T 1 . Instead of employing a cathode-ray tube the arrangement may be employed to control the deflection of a light spot projected on to a sensitized surface.

An extension 21 of the eccentric 16 has a projection (40) Fig. 3 (not shown), which defines together with a casing 33 secured to the shaft 14 a pair of chambers (37A, 37B) connected to sources of liquid under pressure. One chamber (37A) is supplied with liquid under a variable pressure and the other (37B) is connected to the interior of the housing 10, which is at a constant pressure, by means of connection 46 to the inlet channel 28. The eccentric 20 will assume a phase displacement relative to the eccentric 16 in which the forces acting to rotate the eccentric 20 relative to the shaft 14 due to the pressures in the chamber 27 and the chambers (37A, 37B), Fig. 3, in the casing 33 are balanced. Stop means are provided to limit the maximum relative rotation of the eccentric 20 and shaft 14 to 180 in order that the maximum effective capacity of the pump or motor may be varied from zero to a maximum. The liquid supply circuit to the chamber (37A) in the casing 33 under variable pressure may have a safety valve to prevent overload. Each eccentric has a plurality of radially arranged pistons associated therewith, Fig. 2 (not shown). Needle bearings 25 and 36 are provided between the piston shoes 17, 22 and the eccentrics and between the eccentric extension 21 and the shaft 14, respectively.

Abstract: 977,047. Writing instruments. W. A. SHEAFFER PEN CO. Nov. 28, 1963 [Dec. 12, 1962], No. 47090/63. Heading B6P. A marking point of the " felt " type consists of a matrix of interconnected particles of synthetic resilient polymer, preferably polyolefine (polyethylene or polypropylene) or polyamide, the voids forming capillary passages for the transmission of ink under writing pressure. If the material be polyethylene, the ink should include, or the point should be coated with, a wetting agent. The point may ber formed by: placing polymer particles in a porous mould and heating while passing gas therethrough to fuse or sinter the particles together; placing a mixture of particles and a water-soluble substances e.g. salt, sugar or starch in a mould, heating to fuse the particles together and then leaching out the substance; forcing a gaseous or liquid solvent through a mass of particles to fuse them at their points of contact; or cutting the point from an extruded rod of the porous material. As shown the point 24 is a friction fit in a pen barrel 12 which holds a supply of ink, the barrel being normally closed by a spring-loaded valve 22 having a downward extension 28 abutting the point. Spring 40 is strong enough so that writing pressure will not cause the point to open the valve; to charge the point, it is pressed in harder to open the valve, the synthetic material being stiff enough to allow this.

A grazing incidence diffraction grating for X-rays in the region of 20 to 600 Angstroms is prepared by coating an optically finished surface with a strongly adherent uniform layer of photographic resist, such as dichromated polyvinyl alcohol, producing a photographic copy of a master grating on the resist layer, developing the copy to leave a resist image formed by parallel strips of resist adhering to the support surface and alternating with exposed strips of such surface, coating with a thin layer of chromium, and removing the chromium on the resist strips by abrasion such as by using cotton wool. The resist image, before being coated with chromium, may be subjected to ionic bombardment in vacuo to clean off resist and other deposits and also increase the bar to space ratio of the final grating. Also the completed grating may be subjected to ionic bombardment to remove any hardened resist remaining after the abrasion process.
